AFFiNE vs Syncthing: at a glance
What is AFFiNE?
AFFiNE breaks a run of dependency-only canaries with a fix for blob uploads after quota changes.
AFFiNE is a collaborative workspace (docs, whiteboard, knowledge base) shipping canary builds across cloud, self-hosted Docker and native iOS/Mac apps. After five canaries of dependency work (piscina security patch, Node.js 22.23.3, Swift EventSource, ESLint v10, a broad dependency refresh), canary.921 fixes server-side blob sync: uploads read the current workspace storage limit, cancellation only hits the matching upload, and failed storage reservations retry more reliably. Before that came a stable iOS Share Extension, MCP Server visibility tied to Copilot, and config-driven OAuth and payment settings.
What is Syncthing?
Syncthing 2.1 is in steady patch mode, with database fixes in each release candidate.
Syncthing's 2.1 line added device and folder groups, HTTP CONNECT proxies, optional block indexing and configurable GUI sessions. Since then every tracked entry is a patch release candidate: 2.1.6 went through four RCs with fixes for introducer permissions, temp-file errors and HTTP keepalive, and 2.1.7 is on rc.2 with SQLite fixes for prepared statements and early garbage collection.

◆ Current state
AFFiNE is a collaborative workspace (docs, whiteboard, knowledge base) shipping canary builds across cloud, self-hosted Docker and native iOS/Mac apps. After five canaries of dependency work (piscina security patch, Node.js 22.23.3, Swift EventSource, ESLint v10, a broad dependency refresh), canary.921 fixes server-side blob sync: uploads read the current workspace storage limit, cancellation only hits the matching upload, and failed storage reservations retry more reliably. Before that came a stable iOS Share Extension, MCP Server visibility tied to Copilot, and config-driven OAuth and payment settings.
◆ Where it's heading
The canary channel is moving from toolchain housekeeping back to product fixes, starting with storage and sync correctness on the server. The three active lines remain mobile capture, making Copilot and MCP switchable per deployment, and getting quota, payment and auth behaviour right for self-hosted and cloud workspaces.
◆ Prediction
A stable release bundling the iOS Share Extension and the recent storage fixes is the most likely next visible move; the entries don't show its timing.
Syncthing
5.0COLLAB
Syncthing 2.1 is in steady patch mode, with database fixes in each release candidate.
◆ Current state
Syncthing's 2.1 line added device and folder groups, HTTP CONNECT proxies, optional block indexing and configurable GUI sessions. Since then every tracked entry is a patch release candidate: 2.1.6 went through four RCs with fixes for introducer permissions, temp-file errors and HTTP keepalive, and 2.1.7 is on rc.2 with SQLite fixes for prepared statements and early garbage collection.
◆ Where it's heading
The project is stabilising the SQLite database backend that came with 2.x, with each patch cycle fixing storage edge cases and discovery behaviour. Releases run through multiple RCs before going stable, roughly every two to three weeks.
◆ Prediction
Expect 2.1.7 stable after rc.2, then further 2.1.x patches focused on SQLite and discovery. The entries don't show what 2.2 will bring.
